The thriller Cracks, along with its as-yet-unnamed sequel, are both set in "a disturbing dystopian future", and follow the tale of teenage protagonist Cal Conway as he discovers he exists in a deliberately-induced coma state.

Commissioning editor Anne Clark signed a deal for world rights with Catherine Pellegrino at Rogers Coleridge White for the books, which will be published in 2012.

In May 2011, Piccadilly Press is also set to publish Green’s first novel Dark Ride. The book, which was sent to the publisher as an unsolicited manuscript, is also a thriller aimed at readers aged 11 and over.

"Piccadilly is very proud to have discovered Caroline Green. She is an exciting new talent with an original voice, and we are delighted to be following up her debut Dark Ride with Cracks,” said Clark.
